@@ -268,11 +271,112 @@ It takes care of getting the document onto the screen.
 <p>To do this in an extensible way, the TextView uses its own kind of model: the <code>VisualLine</code>.
 VisualLines are created only for the visible part of the document.
 <p>The creation process looks like this:<br>
-<img src="renderingPipeline.png" alt="rendering pipeline">
+<img src="AvalonEdit/renderingPipeline.png" alt="rendering pipeline">
+
+<h3>Lifetime of VisualLines</h3>
+When the <code>TextView</code> needs to construct VisualLines (usually before rendering), it first
+determines which <code>DocumentLine</code> is the top-most visible line in the currently viewed region.
+From there, it starts to build <code>VisualLine</code>s and also immediately does the conversion to <code>TextLine</code> (word-wrapping).
+The process stops once the viewed document region is filled.
+<p>
+The resulting <code>VisualLine</code>s (and <code>TextLine</code>s) will be cached and reused in future rendering passes.
+When the user scrolls down, only the VisualLines coming into view are created, the rest is reused.
+<p>
+The <code>TextView.Redraw</code> methods are used to remove <code>VisualLine</code>s from the cache.
+AvalonEdit calls <code>Redraw</code> automatically on the affected lines when the document is changed; and will invalidate the whole cache
+when any editor options are changed. You will only have to call <code>Redraw</code> manually if you write extensions to the VisualLine creation process
+that maintain their own data source. For example, the <code>FoldingManager</code> is calling <code>Redraw</code> when text sections are expanded or collapsed.
+<p>
+Calling <code>Redraw</code> does not cause immediate recreation of the lines.
+They are just removed from the cache so that the next rendering step will recreate them.
+All <code>Redraw</code> methods will trigger a new rendering step, but they will delay it using the WPF Dispatcher using a low priority.
+
+<h3>Element Generators</h3>
+
+You can extend the text view by registering a custom class deriving from <code>VisualLineElementGenerator</code> in the <code>TextView.ElementGenerators</code> collection.
+This allows you to add custom VisualLineElements.
+Using the <code>InlineObjectElement</code> class, you can even put interactive WPF controls into the text document.
+<p>
+For all document text not consumed by element generators, AvalonEdit will create <code>VisualLineText</code> elements.
+<p>
+Usually, the construction of the <code>VisualLine</code> will stop at the end of the <code>DocumentLine</code>. However, if some <code>VisualLineElementGenerator</code>
+creates an element that's longer than the rest of the line, construction of the <code>VisualLine</code> may resume in another <code>DocumentLine</code>.
+Currently, only the <code>FoldingElementGenerator</code> can cause one <code>VisualLine</code> to span multiple <code>DocumentLine</code>s.
